摘要
针对工业生产过程中温度控制系统的非线性、大时滞特性,为实现时滞系统PID参数的自整定,该文提出了一种基于搜寻者优化算法的PID整定控制方法。以典型一阶模型作为控制对象进行仿真,结果表明,利用该算法进行搜索寻优可以实现PID参数的在线调整,使温控系统快速准确地达到预设温度。同时,利用可编程计算机控制器(Pcc)的软硬件平台,采用Automatic Code Generation功能实现了对多温区系统的控制,得到了较为满意的控制效果。
In the paper, with the consideration of the nonlinearity and the long time delay of the temperature control system in industrial production process, a self-tuning PID control method based on Seeker Optimization Algorithm was proposed to achieve the PID parameter self-tuning of the time-delay systems. With the typical first order model as the simulation control object, the simulated results have shown that the strategy can adjust the PID parameters on line and make the temperature of the control system achieve preset temperature quickly and accurately. At the same time, the control of the multi-temperature zones with satisfactory results has been realized by using the new function of Automatic Code Generation of the the software and hardware platform of the PCC.
